Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive ...

 · First, I'll answer your questions directly. Yes, most of our sands (and most sands sold in home improvement and big box stores) have crystalline silica in them because they contain quartz sand grains (which is the common name for crystalline silica). These are the same quartz grains found on % of the ocean, lakes and stream beaches in the US.

 · Silica is a "building block" material that forms rocks, soil, sand, and other parts of the earth. A large amount of the earth is made up of silica. Silica occurs in either a crystalline or an amorphous structure. Over many years, silica in the soil can form into crystalline silica due to natural heat and pressure. Crystalline silica is very commonly found throughout the Midwest, .
